History of Chemistry

Since times immortal when the man come on earth his inquisitive nature implored him to constantly make new discoveries. In Indus Valley Harappan civilizations (500 to 600 BC) metallurgical techniques developed for making copper and bronze articles. In Egyptian civilization the methods of developed to preserve deal bodies as ‘mummies’ and chemicals used for it remain a mystery. Even today we still do not know about the chemicals used for preservation of dead bodies. Egyptians had the knowledge of making soap, dyes, glass, etc. Pyramids of Egypt are examples of their progress. Chemists of Egypt worked for discovering touchstone, universal solvent and position of life. Though they did not succeed in their attempts in the process, they learnt about a process like evaporation, distillation, and sublimation which are of help even today.

For treatment, different systems of medicine were developed, allopathy in Europe, Unani in Greece and Chinese in China. In this context, Bodhayan Baanbhatta, Varah Mihir, Arya Bhatta, Nagarjun, Charak, Gargi, Katyayan etc. contributed significantly. Sage Kanad termed the smallest part of as particle matter/elements. On this basis, John Dalton a teacher from Manchester (England), gave his Atomic Theory in 1808 AD.

Ancient Indians had the knowledge of metallurgy, fermentation and preparation of bases, extracts and distillates. The polish done on the ‘Iron Pillar’ of Mehrauli in Delhi is a subject matter of research because no rusting has occurred on it till date.
